Google Sitemap In "Pending" Status? Don't Worry

If your Google Sitemap file is in "pending" status and you are worried that it will never come out of that status, I would not worry. Google recently posted an announcement that this is a known issue and they are working to resolve it.

The announcement was posted by Google's JohnMu:

Some new Sitemaps submitted via Webmaster Tools may remain in a "pending" state. We are aware of this issue and are looking into it; you do not need to take any action. This will have no effect on your site's performance in search results.
